Air Source Heat Pump Vs Geothermal

The federal government is making tax credits available for geothermal heat pumps through december 2016.

Air source heat pump vs geothermal.

These heat pumps operate at between 300 to 600 percent efficiency even in the coldest weather. Air source heat pumps collect and transfer heat from the air while geothermal heat pumps collect and transfer heat from the ground. The increase in cop of air source heat pumps have narrowed this race. Most air source heat pumps have a lowest operating temperature of 4 f 20 c.

Air source heat pump vs. Both types of heat pumps can also work as cooling systems in the summer transferring heat from inside to outside. Geothermal heat pumps on the other hand can reach efficiencies as high as 600 percent. Air source heat pumps have an efficiency that ranges from 150 to 300 percent while a geothermal heat pump s efficiency can reach 600 percent in the heating mode.

Air source heat pumps on the other hand reach 175 to 300 percent efficiency even in milder winter weather. Unlike the two types of heat pumps mentioned above geothermal heat pumps use the ground as a heat source. After that electric back up heat kicks in which can be expensive to operate. For example geothermal energy will work better in climates in which temperatures dip below freezing from time to time.

An average ahri geothermal unit has a cop of around 3 5 closed loop where the equivalent air source heat pump would have a cop of around 3. The credit allows homeowners to. That said in the comparison between ashps and gshps geothermal wins on efficiency. They work on the principle of capturing existing heat and moving it from place to place.

The basics heat pumps do not generate heating or cooling energy. Geothermal heat pumps are a different story. Energy efficiency geothermal heat pump systems are more energy efficient. Energy efficiency while both geothermal heating systems and air source heating systems work on the same basic premise each has its own advantages and disadvantages.

A heat pump absorbs heat from inside your home and removes it to provide cooling.
